To all rwhom t may concer/n.: A

Be it known that I, CHARLES M. Smm, a citizen .of France, av resident of Paris, France, have .invented a certain new and useful Recuperator Structure, of which the following is'aA specification.

The invention relates to a recuperator structure made up of tiles having vertical openings therein, and built up into parallel' spaced columns' whereby thev above-mentioned openings provide substantially unrestricted vertical 'passages for the air or gas to -be pre-heated, and the spaces between such vertical columns are utilized to provide conduits for the exhaust or waste gases which are to be led through the recuperator. @ne object of the invention is to provide a recuperator structure of the above character wherein the column of tiles will be adef quately braced or firmly held in position in a simple manner, and without miser-tering with the passage'of the waste gases through the recuperator, or necessitating modifications` in its general construction.

It is also desired to dispose such bracing or retaining members for the columns so with relation to the remaining elements of the recuperator as not to interfere with the operations of cleanin the same or regulat-v ing the passage of t e waste gases therethrough.

Another object of' the invention is to construct a recuperator of the above ty e in such manner as to permit ecient regu ation therein of theow of exhaust gases, preferably. both in respect to the entire amount of draft, and to eliminate inequalities in the Y draft in diderent parts of the recuperator.

Further objects. and advantages of the invention will bein art obvious and in part specifically pointe out in the description hereinafter contained, which, taken in connection with the accompan ing drawings, discloses a preferred embo iment thereof; such embodiment, however, is to be considvered merely as illustrative of its principle. In the drawings: v

' Fig. l is a vertical section of a recuperator mede in accordance with the invention.

Fig. 2 is a horizontal section taken on line' 2 2 of Fig 1, looking in the direction of thev arrows. v

Referring to the drawings, the recuperator is shown as embodying a plurality of A plurality of substantially horizontal' plates 7 are interposed at various levels between the adjacent columns l'2 of tiles, thus providing a plurality ofconduits 8 extending acrossthe recuperator from side to side, and which serve to conduct the waste gases into intimate contact with the' tiles, as well" as to provide lateral bracing between adjacent columns and assist in closing lthe lio'ri-V zontal joints between tiles at dierent levels.

The exhaust or waste ases areled to the recuperator in any suitale manner, for example, through an intakeflue 9, from which the waste gas passes into a chamber 10 at one side of the above-mentioned spaced 4columns of tiles, and through the horizontal conduits 8 to a similar chamber 11 disposed at the opposite side of the spaced columns, the waste gas being thus led past the' aircooled tiles until its heat has been given up' as full as possible, and it is finally discharge through a. suitable waste flue 12 indicated'at the right in Fig. 1.

Since the space, at the sides of the recuperator which are parallel to the direction of motion of the waste gas therethrough, ordinarily need not be utilized to provide air or gas passages, it is usually posslble to support such sides firmly by means of masonry walls 13 and '14 which lmay also extend eni tirel'y around the recup'erator, but the walls 15 and 16 are lzspaced from the correspond ing lsides 17 and 18 of the recu erator to provide the chambers 10 and 11 a ove-mentioned.

In order to brace properly the tiles and the several columns 2 against loosening towards the -sides 17 and 18 above-mentioned of the recuperator, there are provided bracing members 19 and 2O respectively within the chambers 10 and 11,vvhich bracing memgli bers bear against the sides ofl the end tiles in the respective columns 2, and serve to retain them inproper position. As is shown more clearly in Fig. 2, such bracing mem bers 19 and 20, which preferably are inthe form of continuous vertical masonry partitions extending the full height of chambers l() and ll, divide such chambers-into a plurality of vertical subdivisions, but do not obstruct portions oi the chambers l0 and l1 which are opposite the-Waste gasfconduits 8, and thus free passage is afforded between the Waste conduits 8, which are respectively between adjacent columns 2 of tiles. rlhe Waste gases, therefore, may pass freely through the recuperato'r to the en# haust flue 12, through any one of the series of Waste gas passages which are in the same vertical plane.

in order to cause the Waste gases to reverse their direction o motion one or more times in passing through. conduits 8, there are provided baille plates'2l and 22 which in the present embodiment entend across the chamber L0 and subdivide it into upper and'lovver sections. The Waste gases in most instances travel through tuo .or more of the horizontal conduits 8 in parallel 7 and the jecting portion 30 which serves a functlon,

recuperato'r,preferably embodies means to distribute the gas evenly between such passages. rhis may be'acoomplished in the end chambers l0 and ll., the chamber l0 in the present embodiment having a delecting member 29 extending' thereinto from the vWall 16. As the Waste gases pass into the ..same Way the Waste gas lpassing chamber l0- from the intake tine 9, their velocity tends to carry the major fraction thereof down to the lower of the two horiY zontal conduits 8 through which the waste gases next pass, but the delector 29 serves to restrict the passage of the gas into such lower conduits 8 sufliciently to cause --a proper amount of the gas to :dow through the uppermost horizontal conduit. ln the downwardly through endl chamber 11 tends to ass most readily through the horizontal conduit 8 which is next above baffle plate 22, and a d'electing member also is preferably provided in this chamber. ln the present form of the invention, the end Wall 15, adjacent chamber 11 is provided with a prosimilar tothat of member 29 previously de- Vco scribed.

Thechambers l() or 11 may be utilized to l accommodate means for regulating the draft of the Waste ases passing through the conduits 8. ln t e present instance this is accomplished in the-chamber l0. by providing dampers 23 cooperating with holes 2e in each of the bao plates 22, the baffle 'plates 21 and 22 being supported inproper position between the' bracing or retaining mem.- bers 19 previously described, and the dampassess-:e

thus tending to jlocalize the flow of such gases through the recuperator.

in recuperators or large size wherein many parallel columns 2 are en'iployed, in some instances the number required of the dempers 23 is reduced, by providing open'- ings 28 in one or more ot the bracing .mehr bers 19 whereby7 waste gas entering 4the chamber i0 through certain ol the horizontal Waste gas conduits 8, may pass through such openings 28 and down `through a damper-controlled opening 24 which serves for several of the Waste. gas conduits. For example, as shown in Fig. 2, the dempers 23 and their openings 2d are provided in connection with the iirst, third and iith conduits 8, counting from the bottom ci the figure, While openings 2S are provided in the second and third bracing members 19 fromthe bottom ot the figure, whereby the Waste gas passing through the second and fourth Waste gas conduits, through such openings 28 and down through the damper-controlled opening 2d which is provided in connection with the third Waste gas conduit. Thus the necessity is avoided of prbviding holes 24 andl dempers 23 in connection with the second and fourth Waste gas conduits, as shown in Fig. 2, and 'it will be obvious that the number oit openings 2S may pass employed may be suited to the requirements y of each particular installation.

A plurality of cleaning openings 26, having suitable removable closures indicated conventionally at 27, are provided inl the wall 16 of themasonry Werl; surrounding the recuperator, in line with each of the waste gas conduits S, and at all different levels ot is held against loosening or shifting transversely of the columns 2, by means of the Walls 13 and 14 in combination with the horizontal plates 7 which 4extend between adjacent columns and serve to maintain the same in proper position. The bracing meinbers '19 and 20 which, as cited above, pretlined in the following claims.
